[ "Cycles HIP binaries disabled due to compiler bugs\n### Tasks\n\n- [x] Enable on Windows (#107098)\n- [x] Enable on Linux (#107662)\n- [ ] Enable Radeon VII (gfx906)\n\n### Background\n\nThere are known bugs in HIP compiler that are causing random build failures when making changes to the Cycles kernel. This is preventing developers from efficiently making improvements to Cycles.\n\nCycles AMD GPU rendering were disabled in Blender 3.6 alpha, so that ongoing work like Principled v2 is not blocked. Additionally light tree sampling is not available for HIP in Blender 3.5. We hope this can be resolved later on in the 3.6 release cycle.\n\nRelevant FIXME's in LLVM amdgpu backend (in fact I suspect we hit the same ones back when we were using OpenCL).\nSIRegisterInfo.cpp#L221\nSIRegisterInfo.cpp#L296\n\nMost recent issues:\n#104085 (#104720 )\n#104669\n#104097\nD16714", "Grease Pencil Proportional Edit \"Connected Only\" fails to delimit unconnected strokes if they are selected\nVersion 2.80 rc3 (Linux 54)\n\n[GP_proportional_edit_bug.blend](GP_proportional_edit_bug.blend)\n\nHow to reproduce:\n\n - Open attached file, remain in edit mode.\n - Note the proportional edit settings and selected stroke vertices.\n # Move around the whole blue stroke, along with one vertex at the tip of the black stroke.\n\nObserve how the black stroke is affected by the selected vertices of the blue stroke, even though the two strokes are not connected and are on different layers. This is not the expected behavior of the \"Connected Only\" setting. The strokes should only be affected by their own vertices, but as long as any vertex of either stroke is selected, they will affect each other as though the \"Connected Only\" setting is ignored!", " Greasepencil Hue/Saturation modifier\nOperating system:windows 10\nGraphics card:GTX 1060\n\nBroken:2.93beta\n\nHue/Saturation modifier can not take effect on fill-gradient", "Grease pencil stroke partially invisible until mouse-up\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30\n\nBroken: version: 2.93.0 Alpha\n\nWhile drawing in the attached scene the stroke is only partially visible.

I've rebooted and tried again. It froze again, only this time when I rebooted it I was greeted by an emergency shell. My root Btrfs filesystem is unmountable. I'm currently performing disk imaging, and will attempt to fix the FS or restore the system from backup.\n\nHere's the screen that I saw after rebooting my laptop after the second lock-up:\n\n\n\nI have a specific .blend file that when loaded on Manjaro Linux will freeze the system. I've tried again booting a fresh Manjaro 20.1.1. However it's a confidential client project and I cannot share it publicly.\n\nI wasn't able to reproduce the problem on Windows 10 running on the same laptop.\n\nI suspect the problem could be in an AMD GPU driver - it's the only thing that I believe has enough system access to mess up a roo t filesystem that was involved. And it's clear the problem was triggered by a certain material in Blender, while rendering with Eevee.\n\nNote that the system won't freeze until I turn on Rendered view. Using Material Preview is fine.\nTwo first time when it happened it was immediately after I have added a mix node to add another texture to an existing image path in an Eevee material.\nI thought that maybe texture sizes could be the problem, as I've been using 3 8K textures, and maybe the laptop's GPU can't handle that, but filesystem corruption should never be the result of that.", "Grease pencil.

The greater the increments between sample count updates the longer it takes to stop the render.\nChecking Task manager shows that after hitting `cancel render` it does keep using the GPU, therefore keep rendering, until it finally stops.\nDuring the time between hitting `cancel render` and Cycles actually stopping the render the entirety of Blender becomes completely unresponsive.\n\nThis is only a problem when actually rendering the scene. Viewport render doesn't seem have this issue.\n\nTest file:\n[untitled.blend](untitled.blend)\n\nHit render and wait a little until the rate samples go up slows down.

So in the first column, we're first creating geometry (which is identical to input geometry); then running the StealFrom field on that geometry, giving us a StealFrom of 0 and outputting new geometry; then running the StealTo field on that output, giving us a StealTo of 0. And of course when we switch the outputs, these fields are evaluated in a different order, leading to different final output.\n\nIt's not 100% clear to me that this is a bug; order of operations at the final output is only implied, and I don't think is specified anywhere in the manual at https:*docs.blender.org/manual/en/latest/modeling/modifiers/generate/geometry_nodes.html# .

[ "UI: Headers and status text display\nTask as follow up of: 92844#issuecomment-924488\n\n## Situation\n\nIn 3.0, the order of the header and toolbar was flipped, to follow a more hierarchical order (first mode and top menu items, then tool settings for that mode).\n\nOne issue that arised was that there could be modes on which the header is emptier than the toolbar, so if the header is transparent, there would be dangling icons (image by Harley):\n\n\nTo fix that (and other issues), the header was removed from \"Region Overlap\", which removes transparency, as mentioned on #92844.\n\nThe other issues have been solved since, so it could be possible to bring transparency back. The issue now is that on transform, the header area gets replaced by certain info on coordinates or settings of the operator being executed (`ED_area_status_text`).\n\n\n\n## Possible Solutions\n\n1. Do not change the transparency of the header when `ED_area_status_text` replaces its content. Fixed in [UI: Header Status Text Changes #111676](111676)\n2. Move the status text somewhere else.\n\nThe status text could be moved to:\n1. Info text on the bottom-left. Makes sense since it's closer to the area where the redo panel shows up, and (usually) closer to the status bar where instructions are present. Mockup by Julien Kaspar.\n \n\n2. Footer (see [attached video](https://projects.blender.orgattachment) for a quick hack demo). This has many issues on its own.\n \n\n3. Info Text on top-left. Main argument against this in the past was that the text could be long, but that's no longer the case since long descriptions go to the status bar since 2.8\n \n\n4. Near the cursor as you move.

For example, a bone or vertex doesn't give access to the object, which is needed for multi-edit mode support.\n\n```\nresult = context.region.find_on_screen_mesh_edge(\n location,\n filter=lambda candidate: candidate.object.get(\"my_property\") == 1 and candidate.vert.co.x > 1.0,\n)\nif result:\n print(result.object, result.vert)\n```\n\nOther space types can support this too.\n\n```\nnode = context.region.find_on_screen_node(location, filter=lambda node: node.type != 'OUTPUT_MATERIAL')\n```\n\n\n### Open Topics\n\n- Would we support a returning multiple hits (callers might be able to use the filter function for this if they really wanted).\n- Should this be a generic function for all types of objects:\n\n```\nTypes could be passed in as an argument. e.g.\n```\n\n```\n`context.region.find_on_screen_item(location, type={'EDIT_MESH_EDGE', 'EDIT_MESH_FACE'})`\n```\n\n- Why limit this to picking? Why not support passing in a bounding box & return it's result, or a polygon and return the lasso result?\n\n *This could be handled as a separate step, mentioning it here to note that it's a possibility but not part of this proposal.*\n\n- We could return an object that stores multiple values, this means if we need to add additional context to the result, it wont break scripts.\n\n```\ne.g: \n```\n\n```\n result = context.region.find_on_screen_node(location)\n if result:\n print(\"Found\", result.node, result.node_group)\n\n```\n\n\n### Scope\n\nWhile this need not implement all data-types initially, these are data-types that could be supported.\n\n- 3D View\n\n - Objects (all types)\n - Armature Edit Mode: Bone, Head/Tail\n - Armature PoseBones: Bone (only)\n - MetaBall: Inner / Outer rings.\n - Mesh Elements: (Vert/Edge/Face)\n - Curve: Vertices & Handles\n - Lattice: Vertices\n - Grease Pencil: Vertices\n - Particle Edit Mode: Vertices\n - Stroke path bezier handles.\n - Gizmos? *(not sure about this one)*\n\n- Image View\n\n - UV Elements: Vertex, Loop, Face\n - Mask: Vertices & Handles\n\n- Node Editor\n\n - Nodes\n - Node Sockets\n - Node Links?

[ "Grease pencil. Artefacts at beginning of strokes\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30\n\nBroken: version: 3.0.0 Alpha\n\nGrease pencil strokes drawn with a stylus have unwanted artefacts at their beginning. Especially noticeable at high radius settings. Related to this, the start of a stroke is often narrower than the artist's intention.\n\n\n\n* Open new document, 2d animation\n* Set brush strength to 1 (not using pressure)\n* Set brush radius to 200 (using pressure)\n* draw several lines with a stylus\n* zoom in to inspect the start of the lines. There are artefacts, a 'lumpy' line close to the beginning of the stoke (see screenshot)\n\n**Notes**\nWhen you draw with deformable physical natural media (e.g. a paint brush, felt-tip) adding pressure increases the size of the mark, even when the tip is not moving over the paper. Other drawing programs also work this way. Currently blender doesn't work this way.\n\nI looked at the source code (gpencil_paint.c). Here's what i think is going wrong with the grease pencil strokes:\n\nWhen the pressure difference between two close adjacent vertices is large this can cause ugly 'lumps' in the line.\n\nCurrently, stylus pressure can be very different between the first and second vertex recorded in a grease pencil stroke. This is because there can be a large time difference between the recording of the two points; The first vertex stores a record of the pressure only at the moment the stylus first touches the tablet, subsequent changes of pressure before the stylus begins to move across the tablet are not recorded in the stroke. Only after the stylus starts moving is the second point recorded with the current pressure.\n\n**Proposed solution**\nAny time the stationary stylus tip is touching the tablet, the drawing routine polls the changing tablet pressure continuously. When the detected pressure is higher than the pressure of the last recorded point, the pressure of the last recorded point is overwritten by the newly detected (higher) pressure. This way, the pressure of the first and second points in a stroke is much more likely to be similar, the width of the start of the line will more closely match the artists intention, and the likelihood of artefacts is reduced.", "Dopeheet (in the Grease Pencil submodule) take account the transform keys of the GP object wen you press jump to previous/next key frames.\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: AMD Radeon (TM) Pro WX 7100 Graphics ATI Technologies Inc. 4.5.14802 Core Profile Context FireGL 21.Q4 30.0.14011.2006\n\nBroken: version: 3.4.0 Alpha\n\nDopeheet (in the Grease Pencil submodule) take account the transform keys of the GP object wen you press jump to previous/next key frames.\nIn this Grease Pencil submudule only the GP drawing keys should be taken into account.\n\n**Steps to Reproduce**\n- Open .blend file\n- Select Grease pencil mode in Dope Sheet\n- Jump to next keyframe \n[#100538.blend](T100538.blend)\nHere a quick video with the issue:\n [2022-08-21 15-13-26.mp4](2022-08-21_15-13-26.mp4)\n\n\n\n", "GPencil: Canvas Overlay becomes inconsistent when both Object and Layer are transformed\nOperating system: Windows\nGraphics card:\n\nBroken: 3.4.1\nWorked: never?\n\nModifying Grease Pencil Layer transforms affects the Canvas overlay, but when both the Object and Layer have transforms the overlay does not describe the drawing plane actually being used by tools.\n\n- Open attached .blend\n- Draw new strokes into the Lines layer\n- Rotate the viewport to view the stroke placement.\n\n", "Grease pencil motion blur color bleeding and noise\nOperating system: Windows-10-10.0.19044-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.95\n\nBroken: version: 3.2.0\n\nRendering objects in front of grease pencil with motion blur causes bleeding of the color behind the grease pencil and a noisy result independent of sample count.\nThis happens for both the stroke and fill option of the grease pencil.\nThis happens for both Eevee and Cycles.\n\nScene setup and Cycles result (note the orange pixels):\n\nEevee:\n\n\nHave grease pencil between two objects with motion blur enabled.\n[GreasyMotion.blend](GreasyMotion.blend)\n", "Grease pencil eraser settings not loaded on startup when using ctrl+LMB with the Draw tool\nOperating system: Windows-10-10.0.18362-SP0 64 Bits\nGraphics card: Intel(R) HD Graphics 620 Intel 4.5.0 - Build 26.20.100.7925\n\nBroken: version: 2.90.0\n\nWhen first opening a blend file, your eraser settings are set to default when using ctrl+LMB with the draw tool, and only update after switching to the eraser tool and using it.\n\n\n- Open attached file (the Stroke object is selected and the Draw tool activated in Draw mode).\n- Draw a line\n- Erase part of the line using the same tool but with Ctrl selected.

The idea was that shader will only work in EDIT mode and if user exists it then it will automatically trigger some operator.\nLine that freezes Blender is `bm.to_mesh(context.object.data)` although it doens’t freeze right away.\n\nWhat I’ve found that if I call operator that edits mesh from bmesh then it freezes Blender entirely.\nCurrently as a workaround I moved operator’s code to some function and call it instead of because `bm.to_mesh(context.object.data)` doesn’t seem to freeze Blender when it’s called from handler without operator.\n\n\nEasy way to reproduce (create default scene, make sure cube is selected, run the script):\n\n```python\nimport bpy\nfrom bpy.types import SpaceView3D\nimport bmesh\n\nclass TestHandler:\n installed = None\n\n @classmethod\n def install(cls, context):\n handler = cls()\n cls.installed = SpaceView3D.draw_handler_add(\n handler, (context, ), \"WINDOW\", \"POST_VIEW\"\n )\n\n @classmethod\n def uninstall(cls):\n try:\n SpaceView3D.draw_handler_remove(cls.installed, \"WINDOW\")\n except ValueError:\n pass\n cls.installed = None\n\n def __call__(self, context):\n obj = context.object\n if obj.mode != \"EDIT\":\n TestHandler.uninstall()\n bpy.ops.test.test()\n print('HANDLER CALL FINISHED') # never printed\n return\n \n print('HANDLER FINISHED')\n\nclass TestOperator(bpy.types.Operator):\n bl_idname = \"test.test\"\n bl_label = \"test\"\n\n def execute(self, context):\n print('TEST OPERATOR CALLED')\n bm = bmesh.new()\n\n # WITHOUT THIS LINE IT DOESN'T FREEZE\n bm.to_mesh(context.object.data)\n\n # still printed\n print('TEST OPERATOR FINISHED')\n return {\"FINISHED\"}\n \nclass TestSetupOperator(bpy.types.Operator):\n bl_idname = \"test.test_setup\"\n bl_label = \"test\"\n\n def execute(self, context):\n print('TEST SETUP OPERATOR CALLED')\n TestHandler.install(context)\n return {\"FINISHED\"}\n\n\nbpy.utils.register_class(TestOperator)\nbpy.utils.register_class(TestSetupOperator)\nbpy.ops.object.mode_set(mode=\"EDIT\")\nbpy.ops.test.test_setup()\n# freezes on the next step\nbpy.ops.object.mode_set(mode=\"OBJECT\")\n```\n\n", "Geo Nodes crash, when updating old node group with new (using user_remap()) \nOperating system: Linux-5.15.21-1-MANJARO-x86_64-with-glibc2.33 64 Bits\nGraphics card: NVIDIA GeForce GTX 1660 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.47.03\n\nBroken: version: 3.1.0 Beta\nWorked: I think it always crashed\n\nLets say I have two geo nodes: **old_node** group and **new_node** group.

Many of these topics can be translated, but not all, as some are not extracted at all to the .po files.

The issue there happens in `walk_keymap_hierarchy()`. If the item in the hierarchy is not a string, it is skipped. This happens for tools defining their own keymap, because they use a function instead of a string as the name.\n\nIn turn, the issue is in `keymap_hierarchy.generate()`. If run in the interface, the hierarchy will contain only strings as topic names. However, if run in the background, some of them will still be functions, presumably because it relies on there being a window manager.\n\nTo verify this, run:\n```\nblender --background --python-expr \"import bpy; from bl_keymap_utils import keymap_hierarchy; from pprint import pprint; pprint(keymap_hierarchy.generate()[5][3][1])\"\n```\nversus:\n```\nblender --python-expr \"import bpy; from bl_keymap_utils import keymap_hierarchy; from pprint import pprint; pprint(keymap_hierarchy.generate()[5][3][1])\"\n```\nThe background version prints:\n```\n ('3D View Tool: Object, Add Primitive (fallback)', 'VIEW_3D', 'WINDOW', []),\n (<function _keymap_fn_from_seq.<locals>.keymap_fn at 0x7f3948a5b2e0>,\n 'VIEW_3D',\n 'WINDOW',\n []),\n```\nWhile the foreground version prints:\n```\n ('3D View Tool: Object, Add Primitive (fallback)', 'VIEW_3D', 'WINDOW', []),\n ('3D View Tool: Edit Mesh, Extrude Region', 'VIEW_3D', 'WINDOW', []),\n```\n\n**TL;DR** `keymap_hierarchy.generate()` doesn’t return a usable keymap hierarchy when run in the background.\n\n", "OpenEXR DWA compression should not apply to non-color data passes\nLinux Mint 17.3 \n\n2.78c\n\nI write you because i've been testing alot with DWAA and DWAB.

I think other glitches are caused by overriding the active theme in `ED_view3d_draw_offscreen()` - although when I avoided this some time ago for similar work on threaded offscreen drawing for VR, this didn't solve the color flickering.\nThe active theme should probably use thread local storage.\n\nBesides that, the preview generation should be thread safe with OpenGL:\n* It uses the draw-manager's own context, which is mutex protected.\n* The non-thread-safe immediate mode API is not used inside the draw-manager.\n* The draw-manager already has workarounds for GPU driver issues with threaded drawing.\n\nA note: We could also speed up Eevee preview generation significantly by using viewport render quality, not final render quality.

This is done by making sure the line width is not less than 1.3 and by modulating its opacity.\nHowever, there is cases where this is not enough. For instance really dense drawings with small lines with little to no curvature still tends to flicker a lot.\nAnother case is when the gpencil strokes intersects the scene geometry. This makes the line less thick to the post process which makes it too small.\n\n## Proposed solution:\nWe propose to implement a Temporal AntiAliasing solution. It is robust and will match Cycles & EEVEE's film filtering if using the same filtering function. This only adds one temporary buffer (low VRAM usage compared to rendering at higher resolution) and is completely self contained (works with transparency and don't interfere with other features).\n\nI propose to only implement this for final rendering since it might introduce flickering that might be annoying while drawing.\n\nHowever this wouldn't solve the issue of gpencil strokes intersecting geometry.\nFor this I propose to erode or reproject the render's depth to match the render sample of the new AA scheme. This should fix the second problem completely.\n\n## Technical details:\n- Implementation just need to be ported from Workbench which has a lighter form of TAA than EEVEE.

And it's particularly problematic in UPBGE (a fork of the old BGE based on the latest Blender source) because a game engine must animate objects in realtime with relatively small number of samples per frame.\n\nUpon an examination from the developers of UPBGE, it is found that the problem is due to the fact that the current implementation of alpha hashed transparency uses the world coordinate instead of the object space, as it is often recommended (e.g. [2017 ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games](p4TYf5DDpbQ)).\n\nIt appears that a simple change from the world to object coordinate fixes the problem as shown in this [test commit (see line 80) ](e0a8638d0b255f2fc6ce778d10dd0d12a467b4d3#diff-2b8bf4f9e10009510d02c14e3659ee032c73f829de5453d6abcdf6a3f884fdfdR80), which produces the following result:\n[alpha-hashed-problem-solved.mp4](alpha-hashed-problem-solved.mp4)\n\nIt's my understanding that the [original author ]() decided to use the world matrix to avoid the difficulties with certain corner cases, like when the object is scaled by an extreme factor.

There are a few options:\n1. Add a modifier with a UI-list interface that sets materials at specific slots.\n2. Add the necessary features to geometry nodes (loop? lists?) necessary to make the behavior completely generic\n3. Just add a geometry node group with enough nodes to handle whatever list of object linked materials the object had.\n", "Geometry Nodes Baking\nAs mentioned on the [blog]() the goal is to support the following features:\n* Editing procedurally generated geometry destructively in the viewport.\n* Prepare and manage simulations for the render farm which shouldn't need to run the simulation itself.\n* Explicitly cache parts of the node tree to avoid recomputing them after every change.\n* Re-time animated geometries, i.e. access geometry generated on one frame in another frame.\n\nAt a high level these goals are achieved by allowing the user to bake still or animated geometry at arbitrary positions in a geometry nodes tree using a new Bake node. The baked data can then be used without having to recompute the inputs of the Bake node. It can be edited destructively using Blender's existing edit modes. Furthermore, the baked data can be imported at specific frames.\n\nImplementing all of these features in one go would be too big of an undertaking, so below are smaller releasable milestones that can be worked on one after another.\n\n## Milestone 1: Bake Node\n\nAfter this milestone users will be able to bake still or animated geometries at arbitrary positions in the node tree. The main use cases are:\n* Prepare simulations (with optional post-processing) for a renderfarm.\n* Speedup working with very heavy node trees (e.g. static landscape generation) by explicitly caching the generated data.\n\nThere are a few requirements for this milestone:\n* New Bake node with a dynamic number of sockets for geometries and their attributes.\n* Baking works by pressing on a bake button in the node itself.\n * For baking the user has to choose between still or animated geometry and optionally a frame range.\n * A bake directory on disk has to be choosen.\n* Deleting the baked data should be possible from the node as well.\n* Potential settings and the baked data are stored per Bake node instance. A Bake node that is in a reused node group is counted as multiple Bake node instances. The actual data per Bake is stored in the geometry nodes modifier on the object.\n\nIt may be enough to keep UI changes local to the new Bake node.\n\n## Milestone 2: Manage Bakes\n\nIn production files, there are typically many simulations and other heavy effects that require baking. The goal of this milestone is to give the user tools to manage many bakes.\n\nThere are multiple parts to this which could potentially be split up into somewhat independent tasks, but I keep them together until further discussion happened:\n* Support naming Bake node instances.\n * While working with just Bake nodes in the node tree, this is less important, because the location of the Bake node in the tree \"identifies\" it to the use. When dealing with many Bake node instances at once, one can't rely on their location but needs to use names.\n * Just using node names does not work well for this, because a node only has one name but might be reused many times.\n* Support tagging Bake node instances.\n * As we've seen in the intro, not all baking happens for the same reasons. Therefore it is important that tools that work with multiple bakes can filter what bakes to work on.\n * Supporting custom tags can help the user organize baked data.\n* UI for dealing with all bakes in a scene or file.\n * There should be some kind of UI list that shows all the Bake node instances.\n * It should show which data is currently baked and which not.\n * Filtering can happen using tags and object selection.\n * Various new operators can work on multiple bakes at the same time: bake, delete bake, set bake directory.\n* Python API for dealing with baked data.\n * While the UI we provide for managing baked data should be good enough for most use cases, it seems unrealistic that we can provide all the tools that a larger production needs out of the box. Therefore, it is necessary to make it easy to manage bakes from addons as well.\n\n## Milestone 3: Import Bake\n\nThe Bake node does two things implicitly, it indicates where in the node group the baking happens and it also imports the baked data. Having both of these in the same node is desirable for most use cases, but sometimes it's benefitial to split both tasks. For example:\n* Baking an animated geometry and the loading it at different frames for re-timing.\n* Load multiple baked frames of the same Bake within the same frame.\n* Baking a geometry in one .blend file and then loading it as a cache in another.\n\nAll of these use-cases turn our baking format into a more general purpose interchange format like Alembic that is Blender specific. Baking into other formats will be possible eventually as well, but it not part of this project. Using a custom format allows us to optimize it for our needs and avoids the problem that Blenders data does not always map 1 to 1 to how data is stored in common formats. Also see [this](105251) task.\n\nThe import can be done with a new Import Bake node which takes a (file) path and a frame as input and outputs the geometry. There are some problems that need to be overcome:\n* The Import Bake node ideally has the same sockets as the corresponding Bake node, but this can't be guaranteed when they are in separate .blend files.\n* While not supported yet, it will be possible to pack baked data into the .blend file. Therefore, the path input is sometimes a path on disk and sometimes some internal identifier.\n* It should be possible to use the combination of a Bake node with one or more Import Bake nodes within a node group without having to hard code the file path for all of these nodes. Therefore, it seems reasonable that the Bake node also outputs where the baked data is stored. Also see [this](29266) older proposal.\n\n## Milestone 4: Editing Baked Data\n\nThe idea is that the user can just go into edit, sculpt or other modes on the baked data and edit it in place. For animated geometries, every frame can be destructively edited separately. The goal here is not to record all manual edits the user did. After baking again, the edits will generally be gone.\n\nWhile this might seem like a small feature, if done right, it can have huge impacts on the way people work with geometry in Blender in the long-term. That is because it could theoretically allow us to get rid of the idea of \"original geometry\" in Blender (e.g. the mesh referenced by `object->data`). To give a glimpse into what could become possible: Adding a cube object could just add an \"empty\" object with Cube node in geometry nodes. This allows the primitive mesh to remain procedural. Going into edit mode could implicitly (or explicitly) add a Bake node and bake the cube so that it can be edited destructively.\n\nAs for this milestone, the target use cases are more minor and mostly revolve around fixing up \"bad\" data in animated geometry. For example, in a particle simulation, a single particle got too close to the camera and blocks the entire view. It should be possible to just delete it manually. \n\n## Parallel Track 1: UI for Unused Nodes\n\nThere are various situations in which nodes in a node group are unused:\n* Nodes not connected to the output.\n* Nodes that would compute the unused input of a Switch node.\n* Nodes that were used to compute a simulation that is now cached.\n* Nodes that compute the inputs to the Bake node which is now baked.\n\nCurrently, there is no obvious way for the user to determine which nodes have been evaluated by the last evaluation. However, this information would be very useful because it allows seeing at a glance when data is cached/baked.\n\nLogging the set of nodes that has been evaluated is relatively [straight forward](107780). However, we still need the a good UI for these nodes. The obvious solution is to just gray out these nodes. While that can work, it's not ideal because the nodes can and should still be editable and graying out usually indicates that the user is not expected to edit them.\n\n## Parallel Track 2: Store Baked Data in .blend File\n\nWe already support packing external files into .blend files. That system just needs to be enhanced to also support baking entire folders full with baked data. Ideally, it is possible to load the baked data lazily when loading a .blend file, but that's probably quite a bit more challenging. It remains to be seen how much of a performance hit loading all frames at once has.\n\n", "Mirror Vertex Group inherits the \"All Groups\" setting from Weight Paint mode > Weights > Mirror\nOperating system: Windows-10-10.0.19045-SP0 64 Bits\nGraphics card: NVIDIA GeForce RTX 3070 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.99\n\nBroken: version: 3.6.2\nWorked: I am not sure, probably never\n\nMirror Vertex Group (1) function (from Data tab, Vertex Groups menu) seems to inherit settings from Weight Paint mode, Weights menu, Mirror (2) function.

The reflection is accurate. The object “Water_Large” shows the result with bump mapping applied. Naturally, the reflection is distorted because of the angle of the waves created on the reflection. That is normal, but the reflection of a portion of the rectangles is offset with wrong placement.\n\n**The problem:**\nFor a reason that I really cannot explain, the rectangles of 45 degrees are reflected vertically on the water surface from a precise horizontal position. Without expecting perfection, the reflection should have been displayed with an average of 45 degrees on the water. It is like a threshold where the reflection logic changes See the screenshot and check where the red arrow is for an indication.\n\n* On the screenshot “Camera 1 - 2 meters high”, we can see the reflection making a steep angle at a precise horizontal position on the water.\n* On the screenshot “Camera 2 - 20 meters high”, we can see the problem not being as present as on camera 1. There are still some artifacts.\n\n**Observations:**\n* The problem tends to disappear as we increase the camera distance from the water surface.\n* Furthermore, the problem is less apparent when the noise scale of the texture node used to create the height factor of the bump mapping is lower. You can play with the parameters of the “Water\" shader.\n* The objects closer to the camera are lower in the image height and also show are a more natural reflection (the rectangle at the right for example).\n\nAs you can see on the screenshots, a part of the far objects is being reflected correctly on the water surface, but the majority of the color is not aligned with the angle of the object. Strangely, the objects are being reflected at 45 degrees from the far horizon line and suddenly, from a virtual horizontal line, they start reflecting vertically as if the objects were totally vertical. And that happens at a precise vertical height on the water surface. This is exactly where the problem happens.\n\nFor years, I have never seen any issues with reflections. If you have a scene with a city skyline in the horizon, you are less likely to see that kind of artifacts. In the present case, we have the equivalent of skyscrapers, but at 45 degrees.\n\nI also tried with Blender version 2.93 and the problem is the same.\n\nBefore reporting this bug, I looked at the scene setup. To validate the nature of the problem, I decided to take into account the following factors. \n* The bump height and the distance are relatively low. Nothing exaggerated here to mess up the results.\n* The height of the camera is at 2 meters from the water surface, which is about the height of a human. Nothing exaggerated once again.\n\nI was not sure if that was a bug in Cycles or a limitation. I relied on the definition that has been given to me, “if it works as expected”, and clearly it is not working as expected.

Each node is only called once this way).\n- [ ] Render display in Image window, for a window previously showing UV editor, doesn't restore correctly. (#26828). Code for this is too much spread around and fuzzy, needs full revision.\n- [ ] Object transform is not possible during rendering #37019\n- [ ] Don't render and warn when a driver or pre-render script can't be executed, a texture is missing, physics are not baked.

[ "Multi-Object Properties Editing\nIn Blender, we want to make it easier to set values for multiple objects, bones, strips, keys and other items at once. \n\nCurrently you can do this in limited circumstances, but you have to right-click on a value after you've changed it and pick Copy to Selected from the menu or hold Alt while editing values. This not only slow, but also very hidden, and the Alt-key conflicts with Emulate 3 Button Mouse. Lastly, it isn't clear at all to users which values work for multi-editing, and which values don't.\n\nHere's how we would like to solve it:\n\n\n## Selection vs Active\n\nThe concept of ***active*** in Blender means that we only show properties and only affect the active object or item. However, if we want to better support multi-item editing, we must start by making it so the Properties reflects the ***selection*** rather than the ***active*** item, of which there can only be one. Going forward, by default the Properties will be set to reflect the selection instead. This could be controlled in the Properties like so:\n\n{[F8363009](Screenshot_2020-02-22_at_17.34.54.png), size=full}\n*(The search box is added here to reflect how the Properties will be updated when that item is also added, but is a separate feature)*\n\nIf set to ***Active***, the Properties will continue to function as it does today, only showing properties for the active item.\n\n## When there are multiple selected items\n\nWhen the user has selected multiple items, a few things change:\n\nInstead of showing the name of the object at the top, Blender tells the user how many items are selected:\n\n\nIn the list of tabs, only properties sections are shown that are common among the selected items. For example, if you select a text and a mesh object, we don't show Modifier, Mesh or Curve Properties, since these properties only exist on a subset of the selected objects:\n\n\nThis rule also goes for individual panels. Here, both a Sun and Spot light are selected, and we only see properties that are shared between them. A note at the bottom clarifies that you are only seeing the shared subset:\n\n{[F8364914](Screenshot_2020-02-23_at_18.49.33.png), size=full}\n\n## When values differ\nWhen multiple items are selected, Blender will compare values to check if they are the same, or if they are different. If they differ, we change the way properties are displayed, like so:\n\n{[F8363037](Screenshot_2020-02-22_at_17.52.51.png), size=full}\n\n\n\n## Manipulating values across multiple items\n\n\n\nFor simply setting a value to be the same. you would simply type a new value, hit Return, and that value is then propagated to the selection.\n\nFor manipulating numbers and sliders relatively, you can just drag on them (like Alt-dragging today), or type the character '=', so the user can type '= -3' to subtract 3 from the value on all selected items.", "Support all attributes in the non-point cloud attribute list\nSee #87827.\n\n* position\n* UVMaps\n* Vertex groups\n(...)\n\nTechnical design discussion: #88460", "Undo in Armature Edit Mode does not undo Custom Properties\nOperating system: Ubuntu 20.04\nGraphics card: Geforce MX230\n\nBroken: 3.5 Beta\n\nUndo in Armature Edit Mode does not undo changes to Armature Custom Properties\n\n- [optionally] In default scene delete all objects\n- Add an \"Armature\" object\n- Go to `Edit Mode`\n- In `Object Data Properties` add a `Custom Property`\n- Change the value of the property (to for example `0.0`) in order to add an Undo step\n- Try undo (`Ctrl+Z`)\n\nThe step is not undone in edit mode.\nInterestingly, changes to the Custom Properties of Bones are correctly undone in Edit mode.\nThis makes it seem that changes to Armature Custom Properties were perhaps missed in the Armature Edit Mode Undo Context.\n\n---\n**Original Report**\n[Video](3RZNWd5tRQI)\nNote when changing the **head size** in the redo panel, you can observe how the number of elements in in the Collection Property `bones_for_delete` grows.\n\n1.

(I shared this on reddit, and it was suggested I create bug for it. \n\nAll I did was delete the bottom face of the mesh since I would not need it, but somehow I created invalid geometry and when I add an edge loop near the end it merges. If I try to inset the faces, it gives me weird end geometry.\n\n(This is what was noted from someone on Reddit: Update: just checked the file and here are my findings:\n\n```\n Adding a loop, be it length ways, long ways, or any other way seems to works just fine with the CTRL-R shortcut\n```\n\n```\n The loop cut tool also works just fine.. except if you try and loop cut around the XY plane instead of the XZ plane (drawing a line around the thinnest faces) at which point the mesh seems to collapse to zero height\n```\n\n```\n Insetting faces also works fine, be it via the tool or pressing I... but if you then try and extrude the inset suddenly the model collapses\n```\n\nOther things of note: the face orientation is inside out for this mesh (turning on Face Orientation in the Overlays menu (two overlapping circles in the header) shows them as red) and the object-level scale hasn't been applied. Fixing both of these doesn't correct any of the above issues -- although it IS normally advised since it prevents a few shading and modelling issues -- but it does, for some reason, change how the errors manifest, like the model collapsing in a slightly different way or the CTRL-R shortcut suddenly causing the same issues the tool version of loop cut and slide has.\n\nConclusion: you've somehow managed to turn this mesh into some form of invalid geometry that Blender can't seem to handle properly. You may wish to report it as a bug, including this file as a demonstration.\n\n- Open .blend file\n- enter edit mode and select face mode\n- press numpad 3 for YZ plane view\n- Add loopcut on visible face side (it'll merge the edges)\n\n---\n- repeat first 2 steps from above\n- press numpad1 for XZ plane view\n# select visible face -> extrude + scale (will merge edges).

They are not related to geometry, and not related to illumination, since even the light AO regions appear noisy. Disabling adaptive sampling or changing the threshold to extremely small values removes the issue. Values for the noise threshold look inadequate in these regions. Setting it to 0.01 gives around 27 out of possible 256 light difference between adjacent pixels in HSL color. In regions with reduced noise, the level looks similar to what it should be, you can see both on the image below. The noise disappears when threshold is turned off, so it's not related to maximum samples count. Same issue does not appear on baking direct or indirect light and the noise level seems adequate. It's not related to denoiser, since it's not working in baked maps (unfortunately).\n\nIt's hard to imagine synthetic scene in which the situation will repeat itself.

It takes several brush strokes to push hair into a different direction and align it. Curves tend to drift away from the brush, especially close to the tips.\n\nA good combing brush should feel almost like a real, physical hair comb. It should \"grip\" the hair without letting it drift out of the brush region, while allowing slippage in the hair direction.\n\n# Current problems\nGoal positions for vertices are correctly computed by the brush and initially applied. But then segment length and collision constraints get solved, which moves points away from initial positions. Large brush strokes in particular cause large corrections for length constraints, which diminishes the brush effect.\n\n\nEspecially points at the tip tend get corrected so much that the initial displacement of the comb brush is quickly lost. That is because the length constraint works from the root upwards and only moves the end point of each segment. This \"follow the leader\" solution has the advantage that it only requires one iteration for a perfect length constraint, but the downside is that it artificially overcorrects curve tips. This issue has been described in section 3.1 of \"Fast Simulation of Inextensible Hair and Fur.\" (Müller et al.).\nFTLHairFur.pdf\nRecently a correction factor was introduced (#104589) to make curve tips more responsive, but only partially solves the problem.\n\n# What is the desired behavior?\nCombing should feel like a physical comb. Hairs between the teeth of a comb are constrained in their lateral movement, but can move (with some friction) along the direction of the hair.\n<img src=attachment width=\"300\">\n\nThis suggests that, rather than just an initial point offset, combing should be implemented as a constraint itself. This gives greater control over the priority and weighting of brush influence relative to other constraints. The solver can then try to satisfy segment lengths, collisions, and brush constraints at the same time, rather than overriding brush goals immediately.\n\n# Irrelevant aspects of real combs\nReal physical combs are open to one side to make inserting hair easier. If that side faces down the hair will fall out. This is not a feature we need to replicate. Instead the hair should generally be restrained laterally, but move freely in the longitudinal direction.\n\nReal combs also only work if held at a right angle to the hair direction. Brushes in Blender don’t usually have an orientation, so we can assume that this is always the case.\nCombs are also generally planar, while Blender brushes are spheres or cylinders (depending on projection mode). We don’t need all hair constraints to lie in the same plane.\n\nReal hair has some friction when dragged through a comb. This is a useful feature because it extends the influence of the brush beyond the immediate brush position. But we can simplify the brush and assume a moderate constant amount of friction with a simple tool setting (or disable friction altogether).\n\n# Formulating a comb brush constraint\nAll existing curve editing features can be understood as a simplified position-based constraint system. The goal now is to define an *objective function* that describes a suitable \"comb constraint\" and improve the curve constraint solver so that it supports this new constraint in addition to existing length and collision constraints.\n\nAn formulation of such a constraint can be found in section 5.1 *Keyhole Constraint* of \"A robust and efficient Lagrangian Constraint Toolkit for the Simulation of 1D Structures\" by Adrien Theetten.\nTheetten-2009-JCAD.pdf\n\nThe constraint minimizes the distance to a goal point. The goal is found at the beginning of the stroke by looking on each curve for the closest point to the brush center. The key difference to a simple \"grab\" constraint is that the point parameter `u` along the curve is also a variable, meaning that the point can slide along the curve to minimize deformation, as long as the deformed curve still goes through the goal point.\n\nIt must be noted that the curve has to be differentiable for this to work properly. A simple cubic spline interpolation helps generate a smooth gradient to move the keyhole point in the right direction along the spline.\n\n# Test implementation\nA test implementation shows the improved behavior of the constraint-based brush: The curves are following the brush much more strictly and it only takes a single stroke to align curves.\n\n\nCode: 105769\n\nA few further improvements should be considered for a full feature:\n* The constraint solver should be generalized to support additional constraints in the future.\n* Length constraints should apply to both sides of a segment equally instead of the follow-the-leader approach (solving from the root up). This will require more iterations but make it more compatible with other constraints. Zero weights for root points ensure pinning to the surface.\n* Some simplified stiffness constraints for segment angles can help avoid the \"floppiness\" of curves.\n* Better collision handling is needed. Collision constraints should not attempt to solve length constraints simultaneously, since that only works for the last-solved segment and makes the solution very non-linear.\n* The comb constraint is solved with a linear projection. A few iterations of gradient descent or a similar method for just this constraint type might improve convergence.\n* Currently `segment_length` and similar constraint constants are recomputed at the start of each brush stroke. This is susceptible to drift over multiple brush strokes, as any residual error of the solver is carried over into the next stroke. While improving convergence of the solver alleviates this issue it shouldn't be expected to get a totally accurate solution every time. `segment_length` and other (supposed) constants should be persistent as attributes and only change when e.g. grow/shrink brushes modify them.", "Hair with 'Virtual Parents' acts wrong with clumping noise\nOperating system: Windows-7-6.1.7601-SP1 64 Bits\nGraphics card: GeForce GTX 660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71\n\nBroken: since 2.79\n\n\n\nIf I use clumping + shorter than 4m hairs, virtual parents produces very weird result.\n\n[2021-01-12_06-46-35.mp4](2021-01-12_06-46-35.mp4)\n\n- In the default Cube, add a hair particle system\n- Change emission number to 100 e length to 0.2\n- In the `Children` panel enable \"`Interpolated`\"\n- In `Clumping` set `Clump` to `1.0` and enable \"`Clump Noise`\"\n- Set any value in `Virtual Parents`\n\nHere the file: try to change length, and clumping\n[untitled.blend](untitled.blend)", "Sculpt mode: Draw Sharp brush artefacts when using Scene Spacing in stroke settings\nOperating system: Windows-8.1-6.3.9600-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 660 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 473.04\n\nBroken: version: 3.2.0 Beta\n\n**To reproduce**\nBrush stroke important settings:\n1% stepping, scene stepping\n\nI suppose there is no limiter and with very steep angle step become extremely tight instead to keep constant step.\n\n[2022-05-14_08-04-06.mp4](2022-05-14_08-04-06.mp4)\n\n[untitled.blend](untitled.blend)\n[2022-05-14_08-10-44.mp4](2022-05-14_08-10-44.mp4)\n\n", "Hair particles: rekeying, cut tool, subdividing do not interpolate existing weights (breaking simulation)\nOperating system: Windows-10-10.0.17134 64 Bits\nGraphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.81\n\n\nBroken: version: 2.80 (sub 51)\nWorked: (optional)\nJust click once sometimes work right\n\n\nThis bug happen in both 2.79 and 2.8\nClick and drag the hair cut tool mess up the vertices position, especially after subdividing one or 2 segments of the hair.

When keyframes are dense, the keyframe type becomes almost impossible to see. We agreed that this feature was really useful for organizing the keyframes of a shot, but it needed improvements.\n\n### Current behaviour:\n\n{[F7785806](Set_Keyframe_Type_Visibility_UnSelected_Original_Comparison__copy_1_.png), height=55}\n\n - The size of the keyframe changes, 3 of the 5 options make the icons smaller, making them harder to find\n - The colors are not bright enough.\n - Colors of Selected/Unselected are too similar.\n\n{[F7785842](Set_Keyframe_type.mov), loop, autoplay, layout=left, float}\n\n\n- Keyframe colors become almost impossible to see when there are more keyframes nearby.\n\n---------------------------\n\nSo we came up with a proposal with three main points in mind:\n\n- The user is the one deciding the color/shape\n- Clear colors\n- Clear Shapes (so they are easy to see even for color blind people, as some of them might not be able to differentiate the colors)\n\n### Animation team proposal:\n\n{[F7785822](Set_Keyframe_Type_Visibility_UnSelected_Mock_Up_Comparison2__copy_1_.png), height=50}\n\nThis visualizing way could also propagate to the graph editor, which connects with [D5621](D5621) :\n\n{[F7785827](Graph_Editor_Key_Visibility_Blue_Selected__copy_1_.png), height=250}\n\n\n ---------------------------\n\nBut this proposal fundamentally conflicts with the new way of visualizing the handle type in the dopesheet, as that one changes the keyframe shape as well.\n\n## Current handle type icons\n\n{[F7785830](handletype-current.png), height=50}\n\nFor the animators at the studio showing the handle type in the dope sheet is not really useful, so we keep the option off, but we understand that there are other users that will find these really useful.\n\nI think it's important to understand how we use the dopesheet: \n\n- Since generally every bone has 9 different channels, and we are dealing with a lot of bones in a rig, we keep the channels collapsed in the dope sheet, using the summary or the top channel to make changes, if we want more precise control we'll jump into the Graph Editor.\n\nThe main issues we have with the handle type visualization and the interpolation type visualization are:\n\n### Spring shot file example\n\n{[F7785832](springshotexample.png), height=80}\n\n- When you have a lot of keyframes together the shape difference is so small it becomes really hard to see, becoming more confusing than helpful.\n \n### Open - Collapsed example:\n\n{[F7785835](coolapse-open.png), height=250}\n\n\nWhen the channels are collapsed, the information shown is not reliable. In the example used above, each one of the channels have different handle types and different interpolations. When collapsed there is no single type to be shown, creating misinformation. \n\n---------------------------\n\n## Conclusion:\n\nKeyframe colors are important. We propose an improvement by:\n\n - Clarifying keyframe-type colors and shapes in the dopesheet\n - Suggesting this would be useful in the graph editor too ([D5621](D5621))\n - Offer a switch between handle-type shape and keyframe-type shape (instead of the on/off switch for handle-type shape).\n```\n\n```\n*I’m not not a designer, so this is not final or beautiful design just a proposal to visualize my points. \n" ]

Individual vertices/faces/edges should be selected in the 3d view just as in the current state of blender. In the the UV editor, individual face corners can be selected.

Right assigning a material-less data to object the materials from object are gone too (blender/blender-addons#23805, #52484).\n- [ ] Fix EnvMap update, it can depends on many different things in the scene (#41900).\n\n### Modifiers\n- [ ] Make (at least some) generative modifiers to handle custom normals (like e.g. mirror one, see #44058).\n\n**Array Modifier**\n- [ ] Has been re-written to use bmesh, making 2.63 slower then 2.62, There are areas where speed could be improved, for full info see #30695\n- [ ] Textures from cap objects are completely ignored and no way to override them, see #33578\n\n**Boolean Modifier**\n- [ ] Boolean modifier does not preserve vertices/edges data, see #32203, #33548\n- [ ] Issues with degenerated faces, see #30447\n\n**Decimate Modifier**\n- [ ] Limit decimation along seams (UV vertex color, etc), see #32203\n\n**Explode Modifier**\n\n- [ ] Does not preserve UV maps when using Cut Edges option (#46514)\n\n**Multires Modifier**\n- [ ] Only solid draw mode uses optimized drawing\n- [ ] \"Applying Base\" gives spikes on lover levels sometimes, see #35560, #37997\n\n**Bevel Modifier**\n- [ ] Does not preserve edge custom data, see #35314.\n\n**Simple Deform Modifier**\n- [ ] The bend/taper/twist options use fixed axis, add XYZ options would be nice. #33712\n\n**Skin Modifier**\n- [ ] Skin modifier very slow in some cases, see #40770\n\n**Solidify Modifier**\n- [ ] Curves tesselation creates zero area faces which solidify doesn't handle well #52170\n\n**Remesh Modifier**\n- [ ] Mesh data at extreme distance from origin (2**24), crashes #47209<br>''Note, this is a real corner case - yet its a bug because it shouldn't crash.''\n\n### Physics\n- [ ] Allow using multiple baked caches on a single object (having different frame ranges), see #41896.\n- [ ] Bullet: High memory usage for objects that don't have scale applied (#35799)\n\n**Baking**\n\n- [ ] Generic issue: baking ignores making pointcaches when modifier preview has been disabled. Doesn't need fix - but let's keep track of this for future work.\n- [ ] Point caches do not work well with time remapping (example #35968)\n\n**Cloth**\n- [ ] Proper handling of rendered subframes without baked pointcache, for more info see (#21948)\n- [ ] Proper handling of different vertices placed at the same position with \"Soft Body Self Collision\" option turned on (see (#26956)).\n- [ ] Cloths doesn't allow preview during bake (see (#30490)).\n- [ ] Dupli-group cloth in NLA fails (#29838)\n- [ ] 'Emit from: verts' not working as expected when deforming #36237\n- [ ] Collision of hairs doesn't works properly #39219\n- [ ] Memory optimizations are possible for cloth #42577\n- [ ] Cloth pre-roll feature is totally weird and needs reconsideration #40103\n\n**Collisions**\n- [ ] Collision modifier updates it's data structure even if there are no physics that need it (can be slow), a check should be added to make sure the data is actually needed, see (#26965).\n- [ ] Force fields and collision objects are not included in DupliObjects. This is mostly a design decision (duplis being a purely visual feature), but would be nice to support at least in groups. #35264 #36300\n\n**Hair**\n- [ ] Better handling of collisions & force fields for dynamic hair\n- [ ] Wave kink direction is totally uncontrollable, probably there needs to be a way to define hair tangent direction in particle edit mode.\n- [ ] Adding hair in particle mode only uses the deformed mesh, see (#25689).\n\n**Particles**\n- [ ] Particle emission between frames is only accurate for object level emitter/parent animation, for parenting or constraints an interpolation method needs to be implemented, but before this can be done pointcache code has to get some changes too. See (#36516) for more details.\n*; Parent animation is now supported {{GitCommit|c24a23f. Similar issue still persists for non-animated parents (e.g. rigid bodies) though #39923\n- [ ] Reactor particles\n- [ ] Conversion from some old files could be better\n- [ ] Vector blur + particles being born/dying doesn't work properly, see (#23320).\n- [ ] Metaballs don't work with particles when the particle view setting isn't \"render\", see (#25794) for more info.\n- [ ] \"Constructive modifiers before particles\" is still an open issue, but some way to handle this gracefully would be really nice, see (#25838) for more info.\n- [ ] Density of particles can't be animated with animated textures, see (#28212).\n- [ ] Instanced objects do not show in particle edit mode, see (#28431).\n- [ ] Issue with ghosting particles if you don't bake first. (#28116)\n- [ ] Linked groups: Force fields and guides only work if you use \"Effector Group\" feature, set to its own group.\n- [ ] Particle Hair dynamics: stops working after using \"Add tool\". (#30557)\n- [ ] Instanced objects don't draw in Particle Edit Mode. (#31913)\n- [ ] Child particles Interpolated mode only works well for Hair, for other particles it doesn't take particle lifetime into account. (#33390)\n- [ ] Particle emission doesn't support NGons.\n- [ ] Particle Object duplication doesn't work with Mirror modifier (#34705)\n- [ ] Particle systems fail to duplicate for smoke simulation (#34705)\n- [ ] Random distribution of particles fails in specific setups (#35598)\n- [ ] Default point cache step of 10 frames fails in some cases, see #38563\n- [ ] Particles tangent rotation control by vertex group missing, see #35103\n- [ ] Texture doesn't affect grid particles #40404\n- [ ] The particle system needs to be set to 'Newtonian Physics' for texture to influence the size, and with global gravity turned off #28263\n- [ ] Multiple issues with particles rotation #32340, #44088\n- [ ] Particles hidden in viewport reappear during rendering #40463\n- [ ] Particle initial speed is not properly inherited from the parent #41305\n- [ ] Point density textures can not be used to control particles #44901\n- [ ] Particle duplication in general is rather poorly implemented (no relink of used datablocks, no duplication of psettings ID when duplicating objects, …) #45843.\n- [ ] Grid distribution only supports From Dupli Generated, but not UV. Potentially could use nearest face. #48928\n- [ ] Particles aren't spawned correctly, they are sometimes generated at the same location as other particles, or at the object's origin. See #50135 for one scenario.\n- [ ] Particle editmode could have its 'own' [X-mirror] option (and not reuse editmode option). See #53872\n\n**Rigid Body**\n- [ ] Velocities are not cached, which prevents a proper state update when cache has time gaps #50230.\n\n### Image & Video\n\n**Compositing**\n- [ ] DOF Defocus node: fStop close to 128 fails to give good results, stay away from that value! (#24534)\n- [ ] DOF node gives no realistic results as users expect, documentation needs upgrade for it.\n- [ ] Defocus node is very slow when large blur radius is needed, could be optimized somehow (mipmap, summed area table?) (#29481)\n- [ ] Defocus node does not work nicely without a camera controlling the blur radius. This makes external compositing workflows with defocus difficult. At the heart of this is a design conflict, because defocus is not a true postprocessing effect #36745\n- [ ] Fast Gauss (Gabor filter, Young/VanVliet) has bad results for edge cases. Needs image processing guru (#25543)\n- [ ] Check on DPX and ASC_CDL and (#27377)\n- [ ] Map UV makes mapped images blurry, see #31868\n- [ ] Some nodes does not preserve alpha channel replacing it with fully opaque, see #32580\n- [ ] With new compositor, on loading files a compositor doesn't start (for existing buffers), so viewers remain empty as well. #35417\n- [ ] Ghost Glare is of limited use, needs clarification and probably a more sophisticated generic lens flare alternative #30389 #36488\n- [ ] Some node inputs require a single constant value and don't work with image-based per-pixel values (#36585). This leads to confusion when nodes apparently don't work, because nothing prevents linking such variable values into constant inputs. Compositor nodes should keep track of constant values and limited inputs on the node level (also in node groups!).\n- [ ] Compositor gives unexpected results with specific curve mapping due to precision loss, see #36621\n- [ ] \"Full Sample\" merging does not work with the File Output node, sample merging happens only for render result outside compositor. Real-time editing might also be improved to deal with samples better (#36811, #39143)\n- [ ] Accumulation method in the Lens Distortion node causes artifacts on noisy input #37462\n- [ ] Compositor does not support render slots #43260\n- [ ] Scaling down produces artifacts due to lack of ellipse filtering of sampler #51070\n\n**Image formats**\n- [ ] Upgrade our DPX code to read newer or different versions, copy the ImageMagick code? (#24716)\n- [ ] No support yet to output images in user chosen color space. (#37650)", "Eyedropper for props does not work in dialog boxes\nBlender 2.81, 71f2229b0d82\nfor example, in Texture Paint Context Menu\nI wanted to implement something using Operator and context.window_manager.invoke_props_dialog()\nThis is not a bug, but why not do it at the dialog level.\n" ]

A simple example is the \"OK?\" you get when deleting an object by pressing the \"x\" key. The fact that doing so by pressing \"Delete\" instead does not warn is integral to this proposal.\n\nSome of these operators define a property called \"confirm\". `OBJECT_OT_delete` then uses an \"invoke\" callback called `WM_operator_confirm_or_exec` that checks this property and, if set, will show the confirmation message.\n\nIn the keymap editor we see this property as a \"Confirm\" checkmark. In this case \"X\" has it enabled and \"Delete\" has it disabled. We usually justify this difference because the \"delete\" key is nicely separated from other keys while \"x\" can more easily be hit accidentally.\n\n**Immediate Issues**\n\nThe Modelling module has brought up that some operators have confirmations that cannot be configured. These are mostly operators that have their \"invoke\" callback set to `WM_operator_confirm`. That function does not check for a \"confirm\" property and so asks for confirmation every time and cannot be turned off in the keymap. These include \"delete keyframe\", \"delete bone\", \"delete curve\", \"delete track\", \"delete marker\", \"separate bones\", \"separate curves\", \"delete mask\", \"make vertex parent\", etc.\n\nA simple solution to this is to simply fix the operators as needed. Each can call `WM_operator_properties_confirm_or_exec` to add the \"confirm\" property, and then use `WM_operator_confirm_or_exec` for \"invoke\" instead of `WM_operator_confirm`. This would then allow these confirmations to be turned off in the keymaps.\n\n**Proposed Solution**\n\nI don't think these should be configured in the keymap. Most users would find it very difficult to do so. And it doesn't seem to fit this kind of preference. If I desire a warning about an operation it is about the _operation itself_ and not the way it was launched.\n\nI think we should abandon the use of having an operator \"confirm\" property and instead move this configuration to a new section of user Preferences. I think we should have a new \"Warnings\" section with checkmarks to allow quickly enabling and disabling.\n\nIt is worth considering making this more than just a binary choice. For example, it might be nice if `OBJECT_OT_delete` could allow a choice between \"Never\", \"Always\", and \"When more than one selected\". \n\n**Longer Term**\n\nUltimately, I would prefer that more operators have optional confirmations, disabled by default. That is the reason for #106691. And have a fairly large \"Warning\" Preferences section that allows users to make Blender suit their needs. I think we should use our best judgement to set the defaults for these, but I would prefer to allow users to do things that we don't like. Allow them have no warnings at all or be nagged for every little thing. We are all different and it would be nice to allow for these differences.\n\n", "Crash at the end of preview generation for a deleted datablock\nOperating system: Windows-10-10.0.22621-SP0 64 Bits\nGraphics card: NVIDIA GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 536.99\n\nBroken: version: 3.6.2\nWorked: -\n\nBlender crashes if you trigger the generation of a preview for a data block and then delete the data block itself.

While the file is being written, Blender's UI is gray and unresponsive.\n\nThe problem is not pressing, as usually it takes considerably longer to load the files in the first place. I've asked some artists at the Blender Studio and they didn't really consider the delay when quitting Blender a practical issue. Still, it gets somewhat in the way of quickly testing things with various production blend files, so it could be seen as an issue for developers more than for artists.\n\n### Possible Solutions & Impact\n\n**Simplest solution:**\n\nAs a solution we could introduce a user preference \"Save Recovery File\" that is enabled by default. Disabling this option would:\n- Avoid writing `quit.blend`.\n- Remove the \"File ‣ Recover ‣ Last Session\" menu item.\n- Remove the \"Recover Last Session\" button from the splash screen.\n\n**Alternative solution:**\n\nThe \"Recover Last Session\" operator does not poll the filesystem from its poll function. This means that the operator is available even when the file `${TEMPDIR}/quit.blend` does not exist. Changing this, such that the operator is disabled when `quit.blend` does not exists, means that the above solution would not have to remove the recovery operators when \"Save Recovery File\" is disabled. The operators would auto-detect whether a recovery file is available at all.\n\nThe upside of this solution is that it makes the \"Recover Last Session\" operator appear more reliable, as it refuses to work when it knows it cannot do its job. This would be an improvement regardless of the \"Save Recovery File\" status.\n\nThe downside is that an old `quit.blend` might be lingering around after \"Save Recovery File\" has been disabled. This means that it could appear as if you could still recover, but it would load an older file. This could be avoided by removing `quit.blend` when disabling \"Save Recovery File\", but I'm not a big fan of Blender explicitly removing files that are meant to recover from human error.\n\n### Discussion Topics\n\nThis task is meant to discuss the following:\n\n- Do we want to make it possible to quit without writing `quit.blend` at all?\n- If so, which of the solutions is preferred? Or is there another way to deal with this that's even better?\n- Do we want this as a general option, or something that's enabled only when \"Developer Extras\" are enabled?\n", "Support Scenes Overrides\nCurrently Scenes liboverrides are not really working, changes to its master collection will be lost, resync of scene itself is not possible when the override is the active scene, etc.\n\nSee e.g. #89963 (crash when library override is applied to an object)", "Opening preferences while rendering causes rendering not to be finished (but computing continues)\nOperating system: W10\nGraphics card: 980Ti\n\nBroken: 2.80 19-03-31\nWorked: (optional)\n\nWhile rendering in a separate window, you can go back to main window, open preferences and boom, preferences are opened in the render window.

It should also support more component types besides mesh. \"Connected\" mode still needs to be supported.\n\n### Ready to Implement\nThere are no open design questions, but there may be code architecture questions to answer before work starts. \nFor example, modifiers generally retrieve weights from vertex groups, but geometry nodes do not create vertex groups.\n\nWhenever a problem like this comes up, sometimes it's possible to share code, \nbut it often makes more sense to rewrite or \"duplicate\" code, with the eventual aim of replacing the modifier anyway.\n\n| Name | Note |\n| ---- | ---- |\n| **Remesh** | #89052 Do modes get different nodes?\n| **Curve** | #88702 Requires testing regarding differences with modifier.\n| **Bevel** | #86841 Attribute domains can affect bevel control, custom profile should use proper curve geometry. \n| **Smooth** | #86903 Quite simple, can be generalized to smooth any attribute, not just position.\n| **Solidify** | #89050 Only non-manifold mode supported in the node.

The node could support an arbitrary mirror plane. \n| **Laplacian Smooth** | Looks relatively simple. \n| **Volume Displace** | Should be relatively simple, but should be discussed briefly to make sure it fits into geometry nodes design. For example, maybe supporting attribute grids is a first step. \n| **Decimate** | #89051 This looks relatively simple to convert. This might be an opportunity to make some design changes though. \n| **UV Project** | Should be relatively simple to convert this, but may need to be changed for attribute access. \n| **Weighted Normal** | Many of these ideas could use generalization.

That's why some modifiers have to tell you to \"Enable Auto Smooth in mesh properties!\"\n- Without further configuration, auto smooth **always recalculates** sharp edges. With deforming meshes, it generally makes no sense to change sharp edge flags over deformation.\n - Even understanding this issue is confusing because, as mentioned, auto smooth is portrayed as a property rather than an action.\n- Using custom normals forces calculating normals per-face-corner, even in cases where splitting normals across edges isn't necessary. This is much worse for performance.\n- Custom normals are always stored as `short2` in a special coordinate space defined by the automatically calculated normals. Converting to and from this coordinate space is expensive.\n - This forces calculating automatic face corner normals to view them, even if the custom normals were hypothetically generated procedurally.\n - Custom normal spaces also make per-vertex custom normals impossible.\n\n## Solutions\n\n### Procedural Custom Normals\n\nTwo new geometry nodes features can allow reading and writing custom normals in a procedural context.\n\n1. **Set Custom Normals** has a choice between creating vertex and face corner normals, a vector input, and an option for whether to write normals in the stable-over-deformation custom normals space (the one currently used for custom normals), or as regular vectors.\n - The last part represents another new feature. If they are stored in this \"plain vector\" format, further use of normals doesn't have to recalculate anything, compared to the existing custom space system, where the automatic normals need to be calculated to find the actual custom normal vectors. That works well when normals are set procedurally at the end of modifier stack anyway.\n - With the vertex domain, only the plain vector format would be supported, unless we wanted to add another normal space option for vertices.\n2. The **True Normal** output/node adds to the existing \"Normal\" node. It outputs normals without custom normals.\n - This could be a new node, or a new socket to the existing \"Normal\" node.\n - Versioning would replace existing nodes with this output.\n\nFor the \"plain vector\" format, the regular `float3` attribute type can be used. Potentially, meta-data could tell geometry processing algorithms to interpolate the attribute differently if they support it (a simple case is the \"Transform Geometry\" node). But generally the existing custom normals space `short2` storage should be used if better interpolation is necessary.\n\n#### Curve Normals\n\nCustom normals should be possible for curves too, though with a separate node since the options are different. The existing \"Set Curve Normal\" node can be used to set custom per-point normals. These may be automatically changed later to make them perpendicular with the tangents.\n\nThe creation of a per-curve \"up\" vector attribute to influence the starting direction used for normals calculated automatically with the existing modes could be supported too.\n\n\n### Replace \"Auto Smooth\"\n\n\n_The existing auto smooth option_\n\nBy writing to the `sharp_edge` attribute, we can have the same effect as auto smooth with a geometry nodes modifier. Versioning code replaces the property with this modifier.\n\n\n_The modifier that replaces the property_\n\nThe modifier keeps the same behavior as before, but often it isn't necessary to change the sharp edges in the modifier stack-- doing it once in edit mode is enough. Similarly, applying the modifier can avoid changing sharp edges over deformation and give better performance. Using a modifier also gives an intuitive way to disable the effect in the viewport, without requiring drivers.\n\n\n_This existing edit mode operator is also useful_\n\nTo keep the existing behavior accessible, an new operator with the same \"Auto Smooth\" name can add this modifier. Eventually though, the node group should be moved to the Essentials asset bundle. That can happen as soon as we have a quick way to add node groups assets as modifiers in the property editor.\n\nCombined with the next auto-domain-choice change, this gives proper control of split face corner normals to geometry nodes. Without the auto smooth option, joining meshes with different sharp/smooth attributes would just work, without relying on the first mesh having auto smooth set. Having the final sharp edge status as part of the visible state of the mesh is essential to make this work.\n\nUsing modifiers for this sort of behavior unifies Blender's design to use user-controllable geometry nodes for geometry processing operations. This design is more obvious in the big picture considering a future where \"everything nodes\" improves the consistency, power, and reliability of Blender features, makes UX more consistent, and improves the development process.\n\n### Automatically Determine Necessary Domain\n\nWith the `sharp_edge` and `sharp_face` boolean attributes, we have all the information we need to know whether we need normals per-face, per-vertex, or per-face-corner. This information is important, because the performance difference between the three is quite large. When the mesh is entirely sharp, face normals are enough. When the mesh is entirely smooth, we need to calculate vertex normals. If there is a mix, we need \"split\" face corner normals.\n\nThis change makes the \"Auto Smooth\" property unnecessary, since one of its main uses was to avoid the performance cost of face corner normals. It's easy to figure the necessary normals automatically, completely removing this step in using mixed smooth and sharp shading, without paying a performance cost in the simpler cases.\n\nThe previous workflow:\n- Enable auto smooth\n- Set auto smooth angle, or set to 180 degrees for complete manual control \n- Run \"Shade smooth\"\n- Mark some edges sharp\n\nThe new workflow:\n- Run \"Shade Smooth\"\n- Mark some edges sharp\n\nPartially this is just a performance optimization (enabled by the removal of auto smooth as a property), but it's also a conceptual change. After the change, the sharp shading status is clearly part of the visible state of the mesh that can be \"frozen\", it's only the shading that's automatic. Before, both of those things were automatic, happening only internally.\n\n## FAQ / Common Concerns\n\n1. This disrupts implicit instancing of objects using the same mesh\n - Implicit sharing of mesh data negates negative aspects of this.\n - Applying the modifier removes the issue completely. Since there aren't any other modifiers, there shouldn't be much of a downside to this anyway.\n - In the future, the \"auto instancing\" could take identical modifiers into account.\n2. Managing auto smoothing on many objects may get more difficult\n - As more features are tied to geometry nodes and modifiers recently, this is clearly a more general issue.\n - It's easy to imagine features to add or remove a modifier on all selected objects.\n - The existing \"hold alt\" feature already works with modifier visibility.\n - The \"Copy to Selected\" modifier feature is also important here.\n3. How accessible is the feature now?\n - Extending add modifier menu with assets (#111717) combined with searching of menus and remembering recent searches (all planned for 4.0) addresses this\n - While the location of auto smoothing moves, and has to be relearned, the consistency and flexibility is worth it\n4. This impacts exporter's special features relating to auto smooth\n - It is true that handling auto smooth as a special feature in exporters becomes more difficult. My hope is that the simplification of behavior (no need for the option, just working with sharp tags, etc.) offsets the downside of this.\n5. There is extra \"stuff\" in geometry nodes modifier panel\n - The extra unused panels can be removed one the node panels features make their way to the modifier.\n - The data-block picker doesn't have to be displayed when adding modifiers from assets, but that is lower priority.\n\n## Technical Info\n\n| Sharp Edges | Sharp Face | Normal Domain | Approximate Cost |\n| ----------- | ---------- | ------------- | ---------------- |\n| All True | All True | Face | 1.0x |\n| Any | All True | Face | 1.0x |\n| All True | Any | Face | 1.0x |\n| All False | All False | Vertex | 4.0x |\n| Mixed | Mixed | Face Corner | 10.0x |\n\nA function `eAttrDomain Mesh::normal_domain_all_info() const;` gives us this information.

It intuitively (and, numerically/extrapolatively) should be indistinguishable to the 0.01 sphere. Because its weights aren't correctly interpolated, it instead ends up with a bunch of spikes at each of its original vertices.\n\nThe middle sphere has vertices weighted in a gradient from 0.00 to 0.50. It serves as an example of a feasible real-world application which would be broken by this kind of behaviour. Perhaps the original vertex weights act as a sort of base heightmap for a terrain model, and the changes made by the Subdivision and textured VertexWeightMix modifiers add an extra layer of detail. In this case, the clear and useful behaviour would be for behaviour to be continuous in the transition from 0.01 to 0.00.

It is pretty much the same issue. It requires two clicks on the same object to really deselect the object, whatever the order of the object in the selection. However, if one object has already been selected before deselecting everything, then the same object gets selected with an additional highlight from the new selection (dragging the mouse cursor in the viewport).\n\nShading view:\nPretty similar to the 3D view.\nIf I deselect all the nodes (Alt + A for example) and I drag the mouse cursor to select all nodes, the last selected node is highlighted in white. If I click the node highlighted in white while holding the Shift key, the node is deselected. However, if I do the same thing for the other nodes, it selects the node with a white highlight and I have to click a second time on the same node to really deselect it. The behavior of the last selected item is also present in the 3D View, but not for the Outliner.\n\nThe Compositing view has the same problem and I suspect that the Geometry Node view has the same too (I haven’t tested the last one).\n\nIn general, it requires two clicks to deselect an object with the normal behavior.\n\nThe first click behaves as an “add to selection” click unless the object already had a selection before completely creating a new selection.\n\nIn all cases, there is an issue with deselecting (or excluding) and single object from a selection of objects in different views.

This does not happen consistently on any particular frame. It does not happen when rendering from the command line with `--background`.\n\nTo reproduce, render an animation with the attached Blender file. One in every 50 frames or so are corrupted. Occasionally it gets most of the way through the animation before ever producing a bad frame.\n\nThis file is basically the startup file with two changes:\n1. An attribute node with the name set to \"Color\" is plugged into the base color on the default material.\n2. The sample count is lowered to one. (The issue persists without this, but with a higher sample count, some samples glitch and others do not. The final image is a mix of the glitched and regular samples.)\n\nI have ensured that this is not a problem with my particular Blender settings by deleting everything in `~/.config/blender/4.0/config` and selecting \"Save New Settings\" in the splash screen before opening and rendering the file in the 4.0.0 alpha.\n\nNormal frame:\n\n\nCorrupted frame (as rendered in 2.93, some other versions simply display a transparent hole where the cube was without affecting the background):\n\n\n", "Make saving of `quit.blend` on exit optional\n### Description & Scope of Problem\n\nEvery time Blender quits, when it has something on the undo stack, it will write the current \"undo file\" to `${TEMPDIR}/quit.blend` ([manual](open_save.html#last-session)).\n\nSaving `quit.blend` can take a while when the file is large. While the file is being written, Blender's UI is gray and unresponsive.\n\nThe problem is not pressing, as usually it takes considerably longer to load the files in the first place. I've asked some artists at the Blender Studio and they didn't really consider the delay when quitting Blender a practical issue. Still, it gets somewhat in the way of quickly testing things with various production blend files, so it could be seen as an issue for developers more than for artists.\n\n### Possible Solutions & Impact\n\n**Simplest solution:**\n\nAs a solution we could introduce a user preference \"Save Recovery File\" that is enabled by default. Disabling this option would:\n- Avoid writing `quit.blend`.\n- Remove the \"File ‣ Recover ‣ Last Session\" menu item.\n- Remove the \"Recover Last Session\" button from the splash screen.\n\n**Alternative solution:**\n\nThe \"Recover Last Session\" operator does not poll the filesystem from its poll function. This means that the operator is available even when the file `${TEMPDIR}/quit.blend` does not exist. Changing this, such that the operator is disabled when `quit.blend` does not exists, means that the above solution would not have to remove the recovery operators when \"Save Recovery File\" is disabled. The operators would auto-detect whether a recovery file is available at all.\n\nThe upside of this solution is that it makes the \"Recover Last Session\" operator appear more reliable, as it refuses to work when it knows it cannot do its job. This would be an improvement regardless of the \"Save Recovery File\" status.\n\nThe downside is that an old `quit.blend` might be lingering around after \"Save Recovery File\" has been disabled. This means that it could appear as if you could still recover, but it would load an older file. This could be avoided by removing `quit.blend` when disabling \"Save Recovery File\", but I'm not a big fan of Blender explicitly removing files that are meant to recover from human error.\n\n### Discussion Topics\n\nThis task is meant to discuss the following:\n\n- Do we want to make it possible to quit without writing `quit.blend` at all?\n- If so, which of the solutions is preferred? Or is there another way to deal with this that's even better?\n- Do we want this as a general option, or something that's enabled only when \"Developer Extras\" are enabled?\n", "Eevee crashes when rendering some of the Blender Studio rigs\nOperating system: Windows 10 Home\nGraphics card: Intel(R) HD Graphics 4600\n\nAlso tested on Debian 11 on both GNOME and MATE.

Now this is frustrating to the user because you need constantly switch back to your brush after every ctrl + z. Stupid bug that interrupts the workflow.\n\nNow this bug is not limited to sculpt mode, it happens in vertex painting, weight painting, texture painting and hair sculpt mode.\n\nHowever this bug doesn't happen to most users because for it to happen you need to have two main windows.\n\n* Add a new main window (`Window > New Main Window`) and switch the workspace (say \"shading\")\n* In primary main window: switch to sculpt mode\n* Choose clay strips\n* Press ctrl + z\n* Observe the brush is draw brush and not clay strips 😵‍💫\n\nNote: I think this has to do something with workspace since switching them can fix this bug but also crash blender\n\n[video](https://projects.blender.orgattachment)", "Bug with environment texture\nOperating system: Windows 10\nGraphics card: Nvidia GeForce RTX 3050 Laptop GPU\n\n3.6.2\n\nAfter I checked and unchecked \"Open Shading Language\" checkbox Blender crashed, after that I opened my project and turned rendered viewport the environment texture become a one solid color, and as I was rotating my camera it was changing the color.\n\nBased on an attached .blend file you can go to the Render viewport and take a look at this error.\n\n" ]

[ "Images in image editor/texture pain not saved with file\nOperating system: Windows\nGraphics card: Nvidia-1070\n\nBroken: 2.91.2 (stable)\n\nImages lost from image editor if file not explicitly saved. Saving the blender file does not save the image in any form. If blender were to crash prior to saving the file out, all modifications to the image are reverted back to the last image save, regardless of when blender was last saved. Autosave does not store the image data either.\n\nAs per #45636:\n\n Reproducing is simple:\n - unwrap default cube in whichever way.\n - Hit texture paint, add diffuse slot and paint a few strokes\n - Save image (or pack)\n - Paint a few more strokes\n - Save .blend (ctrl + S) and quit Blender\n - Return -> your step 4. strokes are lost.\n\nSuggested resolution: Have a 'Live edit' option flag in the Image menu of the image editor to enable saving the file as it is changed (similar to the text editor). Write image file on save (save, save as, autosave) if checked.\n\nNB: Bug #45636 was reported Aug 1 2015, 9:03 AM. It's still a problem *6 years later* as per the continued calls for this to be addressed in that thread.", "Texture paint doesn't prompt user to save painted textures\nIf you are painting on a texture in texture paint mode and save the .blend file, Blender doesn't save the texture (even if the texture file is packed). At the very least, there should be a prompt to warn the user that the painted texture has not been saved one way or the other. \n\nWith texture paint so neatly integrated to Blender (it's really pretty good!), an average user reasonably expects ctrl + s to save not just the model, but the texture he/she has been working on. Blender should either A) offer an \"autosave\" feature to keep the packed texture saved or B) feature a prompt that warns the user that the painted texture will be lost unless saved.\n\nReproducing is simple:\n\n1. unwrap default cube in whichever way.\n2. Hit texture paint, add diffuse slot and paint a few strokes\n3. Save image (or pack)\n4. Paint a few more strokes\n5. Save .blend (ctrl + S) and quit Blender\n6. Return -> your step 4. strokes are lost.\n\nI'm filing this as a design issue but this is actually a borderline bug. I've lost a couple hours' worth of work because of this behaviour. I realize the current behaviour is \"by design\" to an extent but IMO making sure the user's work is safe is of utmost importance." ]

When troubled vertex moved top/right face with back normal will disappear. That might be filed as separate report.\n6. Same as - [x] but bottom-right vertex also moved close to top-left one.

I compare it to the Curve Deform modifier as an example of proper deformation. Now, you may say it's an unfair comparison given that curves have an explicit twist that you can modify, unlike hairs. But even without controlling the initial twist of the hair, it's broken in a couple of ways.\n\nFirst, it deforms the mesh unevenly, with some vertices twisting more than others, even in a case where vertices are completely equidistant around the origin and both origins are aligned, like the cube in this image. The selected face and the edgeloop here should be squares but aren't, unlike in the curve deform modifier \nSecond, when changing the length with the Position Slider, the whole thing seems to change twist at once. Instead of having a consistent twist on each point of the path [Particle Instance Mod bug2.mp4](Particle_Instance_Mod_bug2.mp4)\nAs a side note, when using Along Path, finding how to orient your mesh to the hair is unintuitive, always using the global Y axis as the length axis in which I added subdivisions but then twisting weirdly when changing the Axis option in the modifier, I settled for Z in this example.\n\n\nAttached is the same file used in the video, you can open it and move the Position slider in the Particle Instance Modifier, the scale of the Curve Deform modifier example is driven by it so you can see both changing in real time.\n\n[ParticleInstanceTwistBug.blend](ParticleInstanceTwistBug.blend)\n\nWhy do I think this is happening? Well, if you select the object with the particle system, go to the particle properties, and change the length of the hair under the Render>Timing>End subpanel, you can see the problem is the same, basically the twist changes with length. Maybe the modifier should do something different and get the twist from the whole length particle and then scale the mesh instance before deforming or something like that, idk\n\n", "“Surface Deform”-modifier is overwriting the whole modifier stack\nOperating system and graphics card\nFedora 27 / GeForce GT 740\n(OS-independent issue)\n\n2.79a - offical release - 8928d99270f\n\nUnlike the “Mesh Deform”-modifier, which is applying the changes in a relative fashion, the “Surface Deform”-modifier just overwrites the previous modifier/s with the absolute values of the transform.\n\n[bug_report_surface_deform_modifier.blend](bug_report_surface_deform_modifier.blend)\n\nPlease look into the attached blend-file to follow the examples:\n\nExample1: adding two times the same “Surface Deform”-modifier on top of each other yields the same result as just one or in fact any number of copies of this modifier, thus rendering the nature of the modifier-stack here somewhat useless. In contrast e.g. the “Mesh Deform”-modifier would apply each copy of itself as a relative transform, thus building upon the previous modifiers in stack and changing the output-mesh with every copy of itself.\n\nExample2: Using the “Multi Modifier”-option of the “Armature”-modifier usually takes the same data as the previous modifier as input. The results of the previous modifier and the “Armature”-modifiers are then mixed together, using the weights of the Vertex Group as “mixing guides”. But in the case of the “Surface Deform”-modifier being the previous modifier this seems not to apply and the “Multi Modifier”-option takes no effect at all.\n\nExample3: Adding the “Surface Deform”-modifier on top of “Armature”-modifier overwrites the effect of the “Armature”-modifier (and all other modifiers prior to the “Surface Deform”-modifier.\n\n( An additional oddity seems to me that there is no option to control the overall influence of the “Surface Deform”-modifier with a vertex group, as is usually the case with all other deform modifiers. This though is not part of the bug report and rather a small feature request – but if someone is already looking into the above issue, I figured it wouldn't hurt to mention it here as it is probably just a matter of copy and paste from any modifier that already has this implemented - I might be wrong here though of course - please forgive my ignorance.)\n\nThank you for taking your time to look into that issue.\n\n\n", "Skin modifier can produce undesirable geometry\nBroken: blender-2.74-65328fa-win32\nWorked: never as the skin modifier always had problems like that\n\nThe skin modifier sometime fail and generate very bad geometry\n\n[skinbug.blend](skinbug.blend)\nload the attached blend, and see the problem as shown in the screenshot {[F177512](screenshotbug01.jpg)}(the underlying vertices are all symmetrical, as that base was done with the mirror modifier) \nTest with the various x/y/z options in the skin modifier and see how that buggy geometry can move in other place of the generated mesh\n\nOnly way to fix is to try to either move around the vertices or to rescale them (CTRL+A with the skin modifier) , not real solutions if you need all the branches to be +/- the same diameter and at exact locations.", "Regression: Crash with boolean modifier\nOperating system: Fedora Linux 36 (Workstation Edition)\nGraphics card: Nvidia Geforce RTX 3080\n\nBroken: 3.2.1, 3.3 alpha\nWorked: 3.1\n\nCrash with boolean modifier\n\n- Open .blend file\n- In boolean modifier tab -> select `dot cutter` for boolean operation\n[yin_yang-v1.blend](yin_yang-v1.blend)\noriginal file: [F13292564](yin_yang.blend)", "Nonfunctional \"Vertex Weight Proximity\" Modifier's Influence Mask Inversion\nOperating system: Linux-5.4.0-66-lowlatency-x86_64-with-glibc2.31 64 Bits\nGraphics card: GeForce GTX 680/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.39\n\nLast Broken: version: 2.93.0 Alpha\nFirst Broken: version: 2.90.0\nWorked: version: 2.83.13\n\nButton for inversion of Influence Mask (modifiers[\"VertexWeightProximity\"].invert_mask_vertex_group) in \"Vertex Weight Proximity\" Modifier doesn't work.\n\n\n* Open the attached .blend file.\n* Click Invert button of \"Mask Vertex Group\" in \"Vertex Weight Proximity\" modifier (Influence section).\n* Mask is not inverted on the model & Face button of Geometry proximity mode gets wrongly highlighted.

If you use the Defocus node in the compositor, and an animated object as the target for your camera to determine the focus distance, when you press ctrl+f12, the defocus won't animate, stuck at one distance, the one on the frame you had on the viewport before you pressed ctrl+f12. It seems the camera distance based position of the target object is not being evaluated when the animation is being composited. Animating the Distance value of the Camera directly, without an object, works though. And native eevee or cycles depth of field works with animated distance object too. This is not a huge priority or anything. \n\n\nPlay the animation in the viewport and you'll see the distance of the camera focus does change, but render the animation with ctrl+f12 and the defocus doesn't change in the final video.

As viewport rendering and viewport playback are very tight related most changes will impact both of them and all changes should be tested to both use cases.\n\n## Approach\n\n### Phase 0: Preparation\n\n* Select several production scenes that will be used as benchmark (@Hjalti)\n** Scenes from different productions with different rigs and different sizes.\n* Modify blender to profile what is happening during animation playback. (@Jeroen-Bakker \n**Depedency Graph: Depedency Graph has a detailed profiler. Just need to check if it is sufficient.** Draw Manager: Draw manager already has a detailed profiler. We might want to add small changes (for example separate mesh_extraction from preparation) \n** Other: We should keep track of the rest of the time (not inside the Dependency graph/Draw manager) to detect balance shifts in performance\n* Create an automated test that records the timings in a database so we could compare the results and make decisions (@Jeroen-Bakker)\n* Document the hardware/OS's for the benchmark that will be used\n* Perform a base benchmark\n\n### Phase 1..n: Performance Cycle\nWhen doing performance test you do a single change at a time and monitor what that change does to the whole system. To make a change we suggest the next approach\n* Find the current weakest area\n* Do one or more prototypes to solve the weakest link\n* Select the solution.\n* Create design (mention the other solutions as alternatives) and implement the solution.\n* User test the chosen solution. (@Hjalti) \n* Codereview and merge to master.\n\nOnly after we complete a full cycle we can start with the next cycle. We continue this until we reached a workable performance or the year has ended.\n\n\n## Concerns\n\nThis approach tends to be too narrow focused when looking for solutions. When looking for solutions we should keep in mind to look at the whole picture and not limit the solution to the area in focus.\n\n## Known areas of improvement\n\nThis section contains a collection of known issues that we might want to tackle during the project\n\n* DrawManager mesh extraction uses a task pool per mesh.

It is useful to simulate a sparse set of hair curves and then use a **scatter hair** node after in order to generate more hair curves that are conformed to the shape of the sparse set of simulated hair curves.\n\n**Simulation network** (top drop down menu)\nLink to a node network with simulation setup\n\n{[F8674704](image.png), height = 400}\n\n---\n## NODES - ATTRIBUTE\n\nAttributes on hair objects are created in the hair object UI, much like vertex groups on mesh objects. Perhaps these attributes could be picked up during shading in the future? See #78606 (Hair object - design proposal) for more info\n\n---\n\n - Node: Object weight transfer\n - Type: Attribute\n\n**Input weight (top drop down menu)**\nGets value of vertex weight from input object(s). Useful for dynamic weights controlled by modifiers. Input can be a mesh object (see **Input** node in the *Data flow** section in this document. \n\n{[F8674777](image.png), height = 400}\n\n---\n\n\n - Node: UV transfer\n - Type: Attribute\n\nI've been thinking about how to solve multiple uv sets in conjunction with the generation of hair curves. This node is one solution and is rather flexible, since we can sample uv's from any object. Another route would be to decide that we only source the uv's from the growth mesh. Feel free to give input regarding what would be the easiest in terms of development/coding. \n\n{[F8674782](image.png), height = 400}\n\n---\n\n - Node: Hair root proximity\n - Type: Attribute\n\nThe hair root proximity node is very useful when scattering ground vegetation with the **Instance** node. The root mask can be used to make sure that bushes should not grow close to trees for instance.\n\n\n**Radius**\nThe radius in object space of the mask produced from each root vertex of the hair curves\n\n{[F8674896](image.png), height = 400}\n---\n\n - Node: Attribute get\n - Type: Attribute\n\nWhenever the user needs to remap an attribute (multiply, add, clamp etc) she/he can break out the attribute with an **attribute get** node, do operations and then use a **attribute set** node to write it to the hair curves later in the node graph\n\n{[F8674889](image.png), height = 400}\n\n---\n\n - Node: Attribute set\n - Type: Attribute\n\nWhenever the user needs to remap an attribute (multiply, add, clamp etc) she/he can break out the attribute with an **attribute get** node, do operations and then use a **attribute set** node to write it to the hair curves later in the node graph. Usually the attribute is used right after the node, so it's convenient with a ouput socket with Factor.\n\n{[F8679290](image.png), height = 400}\n\n---\n - Node: Geometry intersection\n - Type: Attribute\n\nNOTE: I will add further visual examples to how this works later\n\n**Position (Top drop down menu)**\n- Inside\n - Masks the hair curve vertices that positioned **inside** of the geometry object. \n- Outside\n - Masks the hair curve vertices that positioned **outside** of the geometry object.\n\n\n**Hair component(Bottom drop down menu)**\n- Root\n - For each hair curve: if hair curve root is positioned inside/outside (depending on the variable **Position**), all of the vertices per hair is masked\n- Vertex\n - For each hair curve: If a vertex is positioned inside/outside (depending on the variable **Position**), that vertex and all of the vertices with higher index number per hair curve (\"child vertices\") will get a value of 1 for the hair curve attribute that is specified in the node.\n\n{[F8674898](image.png), height = 400}\n\n---\n## USEFUL NODES FROM THE SHADING EDITOR\n\nAlmost all nodes in the shading editor would be very useful for creating masks for hair. It would be nice to reuse so the functionality is instantly recognized by the user. I need input from developers such as @sebbas if it's even possible to use existing nodes from shading editor.\n\nShading editor nodes is evaluated after the hair is deformed and we will likely want to evaluate these nodes BEFORE the final deformation of the hair. This could cause issues and I'm not sure it's possible to work around it somehow. Seems tedious to rewrite so many nodes.\n\nA lot of these nodes would require an object/geometry input socket in order to define the source (such as \n- Vertex Color\n- Attribute\n- Texture Coordinate\n\n{[F8663900](image.png), height = 700}\n\n\n" ]

[ "Cycles hair settings are scene based - not particle system based\n%%%The cycles hair settings, which are in the particle system menu, can be overriden on a per scene basis, if the particle system is linked through different scenes. This is kind of odd, since you usually want the different users of the same particle settings to share it's attributes, since this settings affect greatly on the shape of the hair. The rest of the attributes get shared but not the cycles render settings. \n\nI'll take this chance to say that this could be in fact a very powerful feature if the override could be chosen, like with a button. Hell, if everything in blender could be overriden on a per scene basis it would be very powerful (as long as it has a visual feedback and the ability to turn it off), and I can only wonder that if it is possible to do it here why it couldn't be done on other settings. \n\nAs of now, however, I think it is better to make a single user copy of the settings when you want to have a special setting for a specific scene, like you do with materials. \n\n\n\n\n - Win 7, 560ti ---\n\n\n - 2.68a, 2.69RC1, 2.69RC2 ---\n\n\n - Steps for others to reproduce the error (preferably based on attached .blend file)---\n\nSimply link items through scenes, put the same particle system on them, and change the cycles hair rendering settings. They will stay only on that scene.\n\n\n%%%" ]

The benefit of such approach is that a generic callback function can be used (without capturing any internal state of the graph). The downside is the more complex routing of relations.\n\nThe simulation nodes took a bit different approach: the nodes modifier has a special lambda callback which checks the node and dependency graph state:\n```Cpp\nmodifier_node->evaluate = [](...) {\n if (modifier_node->flag & DEPSOP_FLAG_USER_MODIFIED) {\n ...\n }\n}\n```\n\nSuch approach allows to access the modification state without extra nodes and relations, but it is not very generic: ideally the modifier-specific logic will be left to the modifier's \"apply\" callback.\n\nFortunately, there is a simple modification to the current nodes modifier callback we can do!\n\nGeneral idea: have a generic modifier node callback (for all node types) which will copy the user-modified flag from the modifier dependency graph node to the modifier data. The modifier's \"apply\" callback then can make decision based on this flag.\n\nPseudo-code of this proposal goes as following:\n```Cpp\nmodifier_node->evaluate = [modifier_index = ...](::Depsgraph * /*depsgraph*/, ...) {\n ModifierData *md_eval = object_eval->modifiers[modifier_index];\n if (modifier_node->flag & DEPSOP_FLAG_USER_MODIFIED) {\n md_eval-> flag |= MODIFIER_USER_MODIFIED;\n } else {\n md_eval-> flag &= ~MODIFIER_USER_MODIFIED;\n }\n}\n```\n\nUse the modifier index since it can be captured at the graph construction time, and will stay available even if the original objects are destroyed (the long-term goal is to allow the depsgraph be fully independent from the original scene after its Copy-On-Write was run). It is a bit annoying to do an index-based lookup in the list, but it is unlikely to show up in a profiler.\n\nThe geometry node modifier can immediately use this new flag. In a longer term the rigid body will do the same or be migrated to the new simulation framework :)\n\n", "Remove unused slots fails with non-mesh objects\nOperating system: all\nGraphics card: all\n\nBroken: 2.83 2.93 3.0daily \n\nwhen object type is Volume or metaball click remove unused slots button.\nWill delete all material slot whether the material been used.\n\nbut if object type is mesh, this action will keep the used \n\n- Open .blend file\n- Material properties tab -> materials specials -> remove unused slots button\n\nTest File:\n[#90338.blend](T90338.blend)", "Some icons cannot be overriden from python (e.g. 'Constraint.mute', 'use_fake_user')\nBroken: version: 3.3.0 Alpha\nWorked: Looks like this was once working in 2.80 (but has stopped working in 2.81)\n\nSome boolean properties apply an offset to their icon depending on the state of the boolean.

However, I also want to be able to see how the sculpt looks under more finalized lighting settings in real-time while I edit and experiment with different sculpting or placement of facial features, for example.\n- I am constantly undoing brush strokes in a sort of error-correction method of sculpting. Naturally, reducing undoing strokes would be more efficient overall, but not being able to see the reverted mesh from undoing strokes absolutely debillitates confidence of an artist when they're suddenly not working on the most updated model.\n- This can cause bad sculpting errors as one looks from one viewport to the other to \"sanity check\" or simply check progress and be fooled into thinking that the models are synced, when they're actually desynced. The artist might not notice this and continue sculpting, which will update both views again, but it can cause unintentional sculpting errors.\n\nI'm not sure if this was a conscious design choice (2.82 also has this problem. I did not test pre-2.79 versions), but if it was, it makes absolutely no sense why there is even the possibility of anything desyncing between viewports, no matter how the artist works.

It seems that Cycles is only partially recognising changes made to the scene in the pre_render, pre_frame, and post_frame handlers. \n\nIn the below zip file there are 3 directories, each containing a blend file with a simple script to demonstrate the issue. The script changes the file output node's base path, and it also changes blender own render.filepath in the output properties panel. The new file name includes the scene camera name (which changes on frame 1 and 3 using markers) and the frame number when the handler updated the filepath/base_path properties, followed by the __0001 added by Blender. For example frame one should read: left cam_updated_path_on_frame_1__0001.png\n\n**Steps to reproduce problem**\n\n\n\n - Unzip [cycles handler bug.zip](cycles_handler_bug.zip)\n - open each of the blend files in place (use 'load UI' as I've set up the workspace for the easiest testing)\n - notice that the blender output is set to 'not set yet', as is the file output node in the compositor.\n - choose to render the animation\n # In the folder where the current blend file resides there will now be two additional folders, one for blender's output, and another for the file output node's results.\n\n\n**Results**\n\n**pre_render handler**\n\nAs expected the camera is incorrect because the pre_render handler happens before the scene has been evaluated. Although strangely some of the information is for the unevaluated frame that the playhead has just moved to (the frame number) and some is for the frame the playhead was on prior to beginning rendering (the camera name which was active on frame 4 before the playhead moved to the beginning of the animation ready for rendering in this example).\n\nBlender's own image sequence output does use the new path which was assigned whilst in the first frames pre_render handler, but on the first frame, the camera name is incorrect and the frame number is correct:\n\n\nThe file output node images however show that cycles didn't recognise that the base_path property had been updated until the next frame. We can see here that the file ending in __002.exr was updated on frame 1, but not used until frame 2, and this continues all the way through.\n\n\n\n**pre_frame handler**\n\nStrangely, although this handler also fires prior to the scene being evaluated (directly after the pre_render handler), this time Blender's own output shows the camera name is now correct, but again, the updated file output node is still not being used until the following frame:\n\nblenders output:\n\n\nfile output node's output:\n\n\n\n**post_frame handler**\n \nBlender's output again is correct, but the file output node's new path is not being recognised:\n\nBlender's output:\n\nFile output node's output:\n\n\n\nThe above can be worked around with code by grabbing the camera from the marker list instead of the active scene camera, but one really major issue for us is that even when locking the viewport prior to rendering, if we update the file output node's base_path, we start experiencing occasional Access Violations and instant crashes, this happens even if the file output node's path is not visible to UI. (perhaps this is related to the reason why the base path isn't being recognised until the next frame?)\n\n\n", "Cycles freeze on render and texture baking (with packed textures)\nOperating system: Windows-10-10.0.19041-SP0 64 Bits\nGraphics card: GeForce GTX 1660 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.72\n\nBroken: version: 2.92.0\nWorked: 2.83\n\nThis broke somewhere between b21ba5e579 and f2b5f731d5\nAssume 99436acde8\n\nBlender freezes on render\nBlender also freezes on texture bake and rendered viewport\nTried on 3 different PCs, all the same\n\nIf textures are unpacked, rendering is fine.\n\nSimply open attached .blend file and hit F12\n\n[render_test2b_delmesh3_simplified.blend](render_test2b_delmesh3_simplified.blend)" ]
